She had met him through a newspaper advertisement, and the two were married just two days earlier - only hours after stepping off a train and meeting him face-to-face for the first time. But James Allen was not the man he claimed to be. His real name was Henry Scott Mausell, and his intentions were anything but honorable. Eleven days later, Hannah’s decomposed body was discovered and the murder investigation began. So who was Henry Scott Mausell? A man with a deeply troubled past—and Hannah was likely not his first victim, but the last in a long line of murdered women. In "Bloodstained: Exploring Michigan’s Darkest Murders Forgotten by Time", author Allie Seibert sheds light on this largely forgotten, and very likely, serial killer.
